Most fans know Dockett as a defensive tackle for the Arizona Cardinals. But he is a social-media monster, using Twitter -- find him at @ddockett -- for all sorts of hilarious things, including asking to borrow a car at the Super Bowl because the rental companies were sold out, pretending to buy a pet alligator and, most memorably, live-tweeting when he was pulled over by a police officer. That exchange included, when the officer said he would call for backup, Dockett asking if he wanted to borrow his phone. Combine a self-effacing sense of humor with a willingness to say just about anything and you have a winner.
